ENGINE-C0 OLING- SYSTEM.

Application filed March 17, 1921.

To all whom it may concern: I

Be it known that we, F RANK X. ALLEN and SYINESTOR WILBURN, citizens of the United States, residing at Del Rio, in the county of Val Verde and State of Texas,, -1ave invented certain new and usefulImprovements in Engine-Cooling Systems; and. we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates broadly 'to improvements in engine cb'oling systems, being es.- pecially designed for use in connection with automobile engines and having more particular reference to what may well be termed a newtype of radiator adapted to take the place of the types of radiators now in use.

Automobile radiators commonly used, embody inlets and outlets having connection with the water jacket of the engine together with a plurality of air-cooled conduits through which the water slowly passes in order to become cooled, this result being accomplished by cool atmospheric air which surrounds and strikes these conduits in thewell known way. It isour intention, and the main object of this invention to do away with radiators of this type and substitute therefor, one embodying a closed tank having the usual filling neck and inlet and outlet'means at its rear face for connectlion with the engine water jacket. The water is placed in this tank, which is shaped very much like radiators now in use, and an aircooled structure is placed in the tank and, surrounded by the water therein, this structure preferably embodying a. plurality of communicating pipes having an air intake for atmospheric air and a discharge intended to communicate with, and supply partially heated air to the carburetor. Thus, instead of passing the water through air-cooled conduits as usual, the water surrounds the aircooled conduits and is cooled in this way.

Another and important object of the invention is to substitute the type of cooling system above described-for the types in use at this time, and to insure a proper circulation of air through the aforesaid air cooled. structure by providing a conduit between Serial No. 453,011.

the discharge of said structure and the carburetor, whereby the suction created in the latter will serve to draw air throughthe pipes of said structure, this arrangement bringing about another advantageous result since it feeds the partially warmed air, passing through said conduit, into the carburetor mixture. Thus, serves the additional function ofso as to mingle with the uel the device a fuel heater and it insures the production. of an extremely desirable, effective, and highly explosive fuel.

, A further object of theinvention is; to generally improve upon devices of this class by producing one of extreme simplicity and durability, which is of such construction' that 1t may be easily installed on conventlonal types of automobiles without necessitating any alterations of the latter -whatsoever, the number of few and so arranged desired, be installed- Other objects vention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and in. which like numerals. are employed to designate like parts throughout the same: x

Figure 1 is an elevational view of a conventional type of automobile engine, showlng my improved cooling system associated therewith.

Figure 2 is an enlarged sectional view taken on the plane of the line 2-2 of Fig. 1 looking in the direction of the arrows.

Figure 3 isv a detail perspective viewof thelwater coo ing device removed from the tan i For the sake of convenience, we have disclosed a part of an automobile engine to enable the reader tounderstand exactly how our improved cooling system'is associated therewith. The type of engine shown is old and well known and needs only to be rethat the device may if by unskilled hands;

' tal are used merely for. the sake of cleardevice by means of a return pipe P anda' As before intimated, we entirely eliminate the radiator now in use and substitute for it, a closed tank 1 which is shaped to permit it to be used on the type of car from which the old radiator is removed. This tankis equipped on its rear side with an intake. 2 communicating with the discharge neck of the engine,- and at its bottom with an outlet 3 with which the return pipe P is connected,- being also provided at its top with the usual filling neck 4. In accordance with our ideas, 1 this tank is'to be filled with a quantity of} Placed inside of the tank is a water' water. cooling device designated generally byt'he numeral 5. By preferenoe, this devlice is made up of a pair of vertically disposed spaced pipes 6 and 6 connected together by a plurality of closely spaced horizontal pipes 7 At this point, l'wish to make it known that the words vertically and horizonness of description and it isto be understood; that the pipes may be reversed'to through them. In both cases, the intake and gdischarge necks project beyond the- -walls of the tank in the manner shown. As

extend in an opposite direction to that shown. The pipe 6 is provided interme- Y diate its ends. with a forwardly extending air intake neck or pipe 8 whiletheremaining pipe 6 is provided, at a similar point with a rearwardly extending air-discharge neck 9. When the devicefis' in positionin the tankgthe neck 8 extends through anopening in the front side of theftanknear' one vertical end of the latter while; the re-.

'maining neck 9 extends through an open I ing in the rear side of the tank, these'necks beingsoldered or otherwise secured. in the openings to prevent leakage ofwater before stated, a conduit 10 in the form of a pipe or tlib is connected with the projecting end of the 'air discharge neck 9 and leads to the carbureter. With this construction and arrangement, it will be seenthat when the engine is in operation, the suction created in the carbureter will serve to suck ,ai'r throu h the intake neck 8, circulate it through t e pipes 6, (i -and 7,.and thus cool the surrounding water inthe tank 1. 1 The air passing @rough these pipes is bound-to.

become slightly heated since the water in the tank is ordinarily quite warmy By leading the conduit 10 to the'carbureter this warm air can be advantageously in troduced into the carbureter so as to mix 'with the fuel in the latter. H e ii'ce, i;t will be seen that our device not only acts to effectively cool the water in the tank, but it has the additional function of serving as a heater for the fuel and accounts for a great 'saving'of gas. At this point, we wish to device therefrom in order to repair or en- 'tirely replace it..

In all probab'lity, a careful consideration of the foregoing description taken in' connection with thedrawings,"will enable persons skilled in this art to obtain a clear understanding of the same. However, to insure that this end will be'accomplished, we will at this point, briefly. review the operation of the device.

As before indicated,

the old or existing radiator should be re-v moved and. my improved tank-radiator be substituted for it so that it will assume the position shownin Fig. 1. When our improved cooling system is in place as indicated'in this figure, "it. will be seen that as the engine is in operation, the suction created in the pipes of the water cooling. device will cause air to be'drawn into the inta e neck 8, circulate through the variouspipes of the structure 5, and thus effectively cool the surrounding water in the tank 1.. Sincethe water in the tank is generally quite warm the-air passingthrough the various pipes of the water coolingdevice will becomevpartially heated and drawn through the conduit 10 and introduced into the carburetor to which this conduit is con- .nected. This warm airmixing with the air ,and gas in the carbureterwill providewi very desirable and highly' efiicient mixture.

In View of the foregoing, further detaileddescription is thought. unnecessary.

' Since probably the best results may obtained with the construction and arrangement. herein shown and described, this con- ?struction and arrangement is taken as a pre ferred embodiment of the invention. However, we wish to be understood that various m nor changes in the shape, size, and

arrangement of parts may be resorted to without departing from the spirit of the invention'or the scope 'of the subjoined claim.
